Abstract (en)
[origin: EP2899801A1] A power-combining circuit at least equipped with: a plurality of amps, named first and second through n-th amps (PA1, PA2-PAn), for amplifying inputted high-frequency power; a plurality of 3dB-hybrid circuits, named first and second through n-th hybrid circuits (HYB1, HYB2-HYBn), for distributing the outputs from each of the amps to two signals for which the phase difference is 90° in relation to one another; two couplers, named first and second couplers (C1, C2), for coupling the signals, among the two signals outputted from each 3dB-hybrid circuit, which are in phase with one another; two filters, named first and second filters (FILTER 1, FILTER 2), for removing a spurious component included in each of the two signals coupled by the couplers; and a back-end-positioned hybrid circuit, named the 0th hybrid circuit (HYBO), for power-combining the signals from the filters and outputting the same. As a result, the provided power-combining circuit is capable of suppressing and absorbing a spurious component produced during power amplification.
